Correction services in Ontario
Ontario crews choose between commercial network RTK, crowd-sourced base stations, satellite-delivered corrections and their own base.
| Type | Typical operator | What to check |
|---|---|---|
| Commercial network RTK | A private provider with stations across several provinces. | How many correction sources serve your area, the published service level and its remedy, and the term. |
| Crowd-sourced network | Independent owners hosting single base stations. | Distance to the nearest base, station uptime, and how each base was surveyed. |
| Satellite or state-space (PPP-RTK, SSR) | A provider broadcasting an error model without a local base. | Convergence time, accuracy and vertical performance. |
| Your own base | Your crew, on a surveyed point. | The survey of the base point, range, and the time spent setting it up and guarding it. |
Coordinates and heights
RTK Premium delivers NAD83(CSRS), epoch 2010.0, on every Ontario connection, and ITRF on request. NAD83(CSRS) and NAD83(2011) are separate realisations of NAD83, so set Canadian projects and controllers to NAD83(CSRS) rather than the US frame. Natural Resources Canada lists 2010 as Ontario's adopted NAD83(CSRS) epoch, which matches the epoch RTK Premium delivers. The Ontario Co-ordinate System under the Surveys Act sets out ten 3-degree Modified Transverse Mercator (MTM) zones across the province, numbered 8 to 17, with a scale factor of 0.9999 at each reference meridian, and UTM zones 15 to 18 span the province for wider mapping. The regulation still defines that system on NAD27 in feet, so check the datum and units on each plan and control sheet before you mix coordinates. Canadian heights follow CGVD2013, which the CGG2013a geoid model turns into orthometric heights from ellipsoidal ones, while older data and many benchmarks still carry CGVD28 heights. Set the project, the controller and the correction service to the same frame, zone and height datum before the job starts.

Industries using precise positioning or RTK corrections in Ontario
Farmland: Ontario had 48,346 farms in 2021, 25.5% of all farms in Canada, on 11.8 million acres of farm area. Most of that land lies in southern Ontario, where seeding, spraying and harvest run guidance that needs a correction holding pass after pass. (Statistics Canada, Census of Agriculture, 2021)
Field crops: Ontario farms grew 2.8 million acres of soybeans in 2021, 54.4% of Canada's soybean area, and 2.2 million acres of corn for grain, 59.9% of the national total. Row crops like these run on guidance lines that repeat season after season, so the correction has to hold the same frame and epoch each year. (Statistics Canada, Census of Agriculture, 2021)
Construction: Ontario's construction industry had 578,900 people at work in 2024, 7.1% of the provincial workforce, and it added 56.6 billion Canadian dollars to provincial GDP. Grading, excavation and paving crews on those sites set out and check their work against design with machine control and rovers. (Government of Canada, Job Bank, Construction sectoral profile for Ontario (Statistics Canada data), 2025)
Highways: The 2026 Ontario Budget sets out a capital plan of more than 210 billion Canadian dollars over 10 years, including approximately 31 billion for highway expansion and rehabilitation. New corridors, widenings and bridge replacements on that network are staked and checked against design. (Government of Ontario, 2026 Ontario Budget, 2026)
